Postmarketing Reports
Hypersensitivity reactions: Skin rash, pruritus, urticaria, arthralgia, myalgia, drug fever, chills, chest discomfort, anaphylactic reactions, and bullous reactions (including erythema multiforme, toxic epidermal necrolysis, and Stevens-Johnson syndrome)
CNS: Headache, giddiness, neuromuscular hyperirritability, or convulsive seizures
Gastrointestinal: Disturbances of taste and smell, stomatitis, flatulence, nausea, vomiting and diarrhea, epigastric pain, and pseudomembranous colitis have been reported; onset of pseudomembranous colitis symptoms may occur during or after antibacterial treatment
Hemic and lymphatic systems: Thrombocytopenia, leukopenia, neutropenia, eosinophilia, reduction of hemoglobin or hematocrit, and prolongation of prothrombin time and bleeding time
Hepatic function tests: Elevation of AST, ALT, serum alkaline phosphatase, serum LDH, and serum bilirubin; transient hepatitis and cholestatic jaundice reported
Renal: Hemorrhagic cystitis, elevation of serum creatinine and/or BUN, hypernatremia, reduction in serum potassium, and uric acid
Local reactions: Pain, burning, swelling, and induration at the injection site, and thrombophlebitis with IV administration
Warnings
Contraindications
Allergy to penicillins or other beta-lactam antibacterials (eg, cephalosporins, imipenem)
Cautions
Serious and occasionally fatal hypersensitivity reactions reported
Clostridium difficile associated diarrhea reported with use of nearly all antibacterial agents, including ticarcillin
Seizures reported when dose exceeded, especially in presence of renal impairment
Risk of bleeding complication
Potential for microbial overgrowth or bacterial resistance
Laboratory tests: High urine concentrations of ticarcillin may produce false-positive protein reactions; clavulanate may cause a nonspecific binding of IgG and albumin by RBC leading to a false-positive Coombs test
Hypokalemia reported
Monitor renal, hepatic, and hematologic function
Pregnancy & Lactation
Pregnancy Category: B
Lactation: excreted into breast milk at low concentrations; use caution
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
